How is Costco for booking? QUOTE]
I find Costco great, have booked two cruises with them now. They seem to have the same prices as the websites of the lines themselves (often hard to compare as I deal in Canadian currency and a bit of a crapshoot to get quotes from some lines in Cdn Dollars without calling).
I do find their website and contact center to be user friendly and easy compare lines. As a bonus, you usually get something extra that you don't get from the lines (e.g. a Costco gift card).
